I have a dynamic HTML table that allows users to enter receipt items in, and they can add as many rows as necessary.
If they forget to fill out a field upon form POST, I want all those rows with the data to stay shown, instead what happens, is they dynamic rows disappear and no values are saved in the one row that shows on default.
How can I achieve having those dynamic table rows shown with the values they've entered to avoid them having to enter all the data again?
